Distribution Monitor (DISTMON)

In a Unicode conversion the system copy causes very highCPU load during the export. Most of the CPU power is spenton the data conversion, especially on processing clustertables.

To avoid bottlenecks it makes sense to distribute the dataload among multiple machines.

The System Copy Tool Distribution Monitor is designed totake advantage of additional hardware (application servers,PCs,...) for the database export/import.

Software and documentation can be downloaded from SAPNote 855772.
